Kepler

Kepler (Kubernetes Efficient Power Level Exporter) uses eBPF to probe
energy-related system stats and exports them as Prometheus metrics.

As a CNCF Sandbox project, Kepler uses
CNCF Code of Conduct

Architecture

Kepler Exporter exposes a variety of
metrics about the energy
consumption of Kubernetes components such as Pods and Nodes.
